i Be it known that I, CHARLES B. Rice, a the United States, residing at and useful Plane, of a specification. This invention relatesto planes of the type which are employed for grooving purposes, although the 1' I tool of the present invention is susceptible of other uses if desired.

The object of the invention is to provide and inexpensive used in a variety can be easily and meet the requirements llulckl) adjusted to work, such for examof different kinds "of plc the grooving of doors and door frames for 'thepurpose of securing the door locks and fittings in position.

; With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in construction hereinafter described and claimed, it being understood precise embodiment of disclosed can be niade within thescope of the claims without departing from the spirit of the invention.

The extreme reaizcnd of the flange :26

is provided with a curved handle 28 which is disposed at a right angle with respect to 5 at. the forward end of the stock. The bit 3 on the bearing face 25, as shown in- Fig. 1. projects in an opposite direction to the bit 3 on the bearing plate .2 as shown in Fig. 2. \Vhen the bearing plate 5 is employed thereforethe stock manipuing used. The bit 3 on the bearing surface 25 projects through an opening formed 1n the flange 26, the upper edge of said opening 30 being inclined so as to be in parallelism with the edge 27 of the flange 26. The bit 3 of the bearing face 25 is mounted in the same way as the bearing face 2. That. is to say it is mounted upon a post 14 which is provided with shoulders 15 and an en larged flange 16 connected with the flange 26, a loop member 17 being fitted around the bit 2 and the shank 7 of the gage member 8 thereof and a plate 18 having a thickened end 19 and set screw .20 as shown in Fig. 8 being employed to tighten the bit and hold it in any osition to which it has been adjusted. T to post 14 connected with the flange 26 of course extends at a right angle to the 0st 14 connected with the base plate 1. This is necessitated by the fact that the two hits 3 are arranged with'their cutting edges at right angles to each other.

If desired, the plate 18 and set screw 20 illustrated in Fi 8 may be dispensed with, and the modifi'e construction of clampin device shown in Fig. 5 may be employe In this clamping device all the 'parts except the late 18 and screw 20 are the same as previously described. In place of the clampim plate 18 a pair of plates 35 and 36 are empToyed, said plates being riveted together at their lower ends as indicated at 37 and being adapted to be forced apart at their upper ends by means of a lever 38 which is pivoted at 39 on cars 40 formed on the plate 3."). When the lever 38 is thrown upward into inoperative position, the upper ends of the two plates 35 and 36 spring to ether and thusrelease the ressure on the cop members 17 so that the bit can be adjusted upward or downward if desired. lVhen the bit has been properly adjusted, the lever 38 I is thrown downward so that the end thereof bears a ainst the late 36 and forces the up" per en of said p ate away from the upper and of the plate 35. The separation o the late causes the necessary pressure to be )ronght to bearon the loop member 17 to hold the bit in the position to which it has been adjusted.

The plane of the resent invention i p vided with a lateral 40 which is adapted to cooperate with the bearing surface 2 in performing certain classes of work in which the groove to'be formed is located some distance away from the edge by which the plane is to be guided. The gage member 40 consists of a plate as disposed gage member shown in Fig. 3, the upper and lower surfaces of which are parallel with the bearing surface 2 of the plane. The plate 40 is so (llSPOSQt'l-Wltl'l relation to the bearing surface 2 that the upper surface thereof is slightly below the plane of the bearing surface 2 so that the plate 40 can if desired be adjusted inward beneath the bearing sur-- face 2. The gage plate 40 is provided atone end with a depending. flange 41 and at the other end with an upstanding flange 42. The upstanding flange 4:2, as shown in Fig. 1 is provided with four threaded open ings 43-43 and 44'44. Connected with either the set of perforations 43-43 or 44-44 is a pair of supporting rods 45 which extend through the flange 26 of the base plate 1 and through a flange 47 formed along the opposite edge of the base plate 1 from the flange 26. The rods-t5 extend loosely through the flange 4T and are adapted to be locked in any position to which they lmve been adjusted by means of set screws 48 whichextend downward through the flange 47 and are adapted to engage the rods 45. By loosening the set screws 48 the gage member 40 can be adjusted a greater or lesser distance away from the base platel. As indicated in Fig. 3, the plate 40 can be adjusted toward the base plate 1 to such an extent that the depending flange 41 will lie beneath the bearing surface 2.and will thus act as a gage for the cutter when working close to the edge by which the plane is being guided. If it be desired to arrange the gage member 40 on the opposite side of the device from that shown *in,Fig.=1 ,'the rods 45 are unscrewed from the flange 42 and are reversed in the flange 47. The flan e42 is then connected with the threaded en s of the rods 45, the pair of threaded openings 43 43 being employed so that the forward ends of the gage member 40 will not project beyond 'the forward end of the 'bascsplate 1. Moreover, the gage plate 40 can be reversed while remaining on the same side of the plane as that shown in Fig. 1. By means of this reversal the plate 40 can be caused to project outward with relation to the flange 42 instead of inward toward the baseplatc 1 as shown in Fig. 3. It will. also thoroughly ple, of grooving the endof a door to receive the door lock or fitting.

The tool of the present invention is strong, simple, durable and comparatively inexpenswe in construction as well as tion. i

efficient and practical in opera- Sllf- .having a gage tongue ing said post and resting against said shoulders, a bit having a shank arranged between said posts and said loop on one side, and an adjustable member arranged between the other side of said post and said loop mem her for tightening the same on said hit.

4. A plane having a bit provided on the rear face thereof with an adjustable ga e.

5. A plane having a bit provided with a cutting edge projecting in one direction, and a gage plate connected with said bit and projecting in the oppositedirection from the cutting edge of the hit.

6. As a new plane bit having and-a gage plate adjusta 1y connected with said shank for regulating the'depth of the cut of said bit.
